    I just bought a 2012 Pete 386, I am experiencing a slight to moderate front end shake as I roll down the road. It does not effect the steering wheel, that I can tell, but has a significant bounce coming from what seems to be the Right front steer area. When going slow through the yard, It feels like there is a flat spot on the steer or even like something is bent! Prolly lean more to the BENT feeling myself. when the steer makes a full rotation at a very low speed, it feels like it hits a HIGH spot, and oblong feeling. Any Ideas?

    I would start with the tire. Easy way to check is to pull them off and switch sides and see if the problem moves to the other side.

    Jack the front end up and spin the tire. See if it's out of round. Could be a tire mounting problem, especially if it was dry mounted. Look at the bead line. While it's jacked up, check wheel end play and kingpins.
